Not sure how to describe it, but the sound seems off when I watch movies and documentaries on bf109.
There is a very noticeable sound, it is like a whistle I suppose, not sure how to describe it… I’ll leave that to the experts.
Can we get the 109 engine sound to match real life sounds, in cockpit and outside?
I thought I knew sort of what you were talking about and then found this:
Exactly 
I’m sure this is something they are working on. I’d imagine this kind of thing is not currently their priority. It’s still a new game, and as we know, Gaijin very much knows what a BF109 sounds like. Their 109 sound design in War Thunder is very good. I am sure they’ll transfer the same sounds over at some point, as well as pretty much all of the vehicle sounds in the game.
Noone else cares, I’m actually quite surprised how the realists are not complaining lol.
Also the mg cannon sounds seem to be a different sound with latest patch?
Can I revive this topic? Would be do great to get real Mercedes engine (?) sounds, one of the biggest draws to Enlisted is it’s atmosphere, please can devs look at that, as well as other plane stuff
